To all whom it may concern:

Be it known that I, ANTHONY 'HOZLAK, a citizen of Austria, residing at Nanticoke, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Submarine Attachments, of which, the following is a specification.

This invention relates to improvements in submarine attachments and it is the principal object of the invention to provide a novel attachment for use on submarine vessels whereby to permit the laying or placing of mines therefrom while submerged, thus, rendering the vessel extremely useful in warfare.

It is a more specific object of the invention to provide means for allowing a person to leave or enter the vessel while submerged without danger of flooding the interior thereof.

ther objects will be in part obvious. and in part pointed out hereinafter.

The invention consists, furthermore, in the novel arrangement and combination of parts of the device, as well as in the details of the construction of the same, all of which will be more fully described in the following specification and then finally embodied in the clauses of the claim which are appended to the specification and which form an essential part of the same.

in the drawings Figure 1 is a top plan of the attachment as applied to a submarine vessel.

Fig. '2 is a vertical transverse section through the same, Fig. 3 is a longitudinal section therethrough and a portion of the submarine vessel, and,

Fig. is a fiagmentary. section therethrough.

Having more particular reference toithe dr wings, in connection with which like reference characters will designate corresponding parts throughout the several views, 1 represents the hull of a submarine vessel in its entirety, one side of the same being provided with a way normally closed by a hingedly mounted door 2. Communicating with the way formed in the sideof the submarine vessel is an inclosed way 3, the sides of which are obliquely disposed with relation to the sides of the submarine as indicated by the numeral 4, whereby to serve as means for deflecting the water contacting Specification of Letters B ate nt.

Fatented a .Le, ieia.

A second door 8 is arranged in pro imity to the outer end of the inclosed way 3'and is mounted to swing inwardly thereinto in by a diver or other operator when so desired. I

Formed in the bottom of the inclosed way therewith and preventing the abnormal I of the way order that the same may be readily opened 3, preferably intermediate the end thereof is an opening communicating with a tank or container 9 arranged therebelow and se cured in a suitable manner to said inclosed way. ihis opening, as will be noted, is normally closed by a vertically movable door 10 hinged at one end to the flooring of the inclosed way and adapted to lie flush with the same'when in its closed position. A. hand hold 11 or other suitable device may be arranged upon the free portion of said door to facilitate lifting of the same toits open position.

linoperation, the diver or other operator when desirin to leave a' submarine vessel provided wit opens the door 2 arranged in the side of the submarine vessel; it of course being understood that the outer door 8 arranged in the way 3 is-closed. EUpon entering the inclosed the improved device first.

way, thedoor 2 is then closed and the operator proceeds to the door 8, opening the same and passing onto the platform 5 from whence he'can ascend by way of the steps 6 onto the inclosed secondary way 7 arranged remove the water accumulated in said way,

the. vertically movable door therein is raised.

to its open position, thus, allowing such water instantly to pass into the tank 9. With the way thus cleared of the water, the operator may then cause the door 2 to be opened and enter the submarine, whereupon sai'd door is again closed.

Obviously, since the ways 2 and 7 and the platform 5 are inclosed, all liability of the sweeping of the operator therefrom during movement of the submarine through a body of water will be prevented.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention.

I claim V 1. In combination with a submarine vessel, a door formed in'-one side thereof,"an inclosed way communicating with said door, means for temporarily closing the outer end of said way, a second inclosed way arranged above the first way communicating menace therewith and opening onto said vessel, and 7 means arranged in thefirst way for removing water therefrom.

2. In combination with a submarine vessel, a door arranged in one side thereof, an inclosed way secured to the submarine vessel and communicating with said door, the opposite sides of said inclosed way being arranged obliquely with relation to the sides of the submarine vessel, means for temporarily closing the outer end of the inclosed way, a second, way arranged above and communicating with said first way and opening onto the hull of the submarine vessel, a tank communicating with the flooring of said first way, and means for normally closing said tank.

In testimony whereof, ll afix my signanature hereto.

ANTHONY HQZLAK.
